Abstract

PURPOSE:To sort long-sized vegetables by weight by automatically measuring the weight thereof while carrying the material to be sorted one by one and automatically sorting them into a plurality of recovery parts on the basis of the result of measurement and recovering them. CONSTITUTION:Many long-sized vegetables a are stored in a hopper 1 and passed through the parallel provided rollers 7a, 7b from the lower part of the hopper 1. These vegetables a fall on a carrier device 9 one by one toward the same direction and are stopped by the stopping projections 8 and carried by a carrier belt 12. A weighing base 3 is provided to the lower part of the belt 12 and the vegetables a are weighed one by one and sent to a sorting means 5. The vegetables a sent to a carrier conveyor 18 of the sorting means 5 are weighed by the pushers 19 arranged parallel to the lateral side part of the conveyor 18. The vegetables are extruded by the pushers 19 correspondent to the weighed weight and recovered at every weight into the respective recovery tools 4 provided to the lower parts of the respective pushers 19. Therefore the long-sized vegetables a are sorted into the grades at every weight and automatically recovered.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sorting device for automatically sorting and collecting so-called long vegetables, such as carrots, cucumbers, and radish, by grade, for example.

[Conventional technology]

Conventionally, the sorting work described above was performed manually.

[Problem to be solved by the invention]

As described above, manual sorting can perform the sorting work accurately and reliably, but when the amount of processing increases, the labor burden on the operator increases, so automation of such sorting work has been desired.

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus for sorting long vegetables that has a relatively simple structure and is inexpensive, yet is capable of automatically carrying out the above-mentioned sorting work.

[Means to solve the problem]

The features of the present invention include a hopper that stores a large number of objects to be sorted;
A conveyance device that carries out the objects to be sorted one by one at intervals from the bottom of the hopper diagonally upward; and a conveyance device that is connected to the conveyance end portion of the conveyance device and automatically measures the weight of each object to be sorted while conveying it. A measuring means, and a sorting means that is connected to the terminal end of the measuring means and automatically sorts and collects the objects into a plurality of collecting sections based on the measurement results of the measuring means while conveying each object to be sorted. It is in.

[For production]

Objects to be transported stored in the hopper are transported individually at a predetermined pitch by a transport device.

Then, while being conveyed continuously from the conveyance terminal end, the weight is measured by the measuring means, and the articles are further conveyed successively and automatically sorted and collected by the sorting means. In this way, the work is carried out automatically throughout the process, from unloading to sorting and collection, while continuously conveying the items.

In addition, if the unloading device is configured to unload the items in a direction perpendicular to the longitudinal direction of the items to be sorted, it becomes possible to reliably place and transport the items one by one.Moreover, if the attitude is changed midway through, the sorting by the sorting means will be difficult. During collection, the material is guided from the transport area to the collection section while rolling, reducing the risk of damage.

〔Effect of the invention〕

As a result, with a rational structure, the sorting and sorting of long vegetables can be performed automatically with a relatively simple configuration, and the work effort can be reduced.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows an automatic sorting device that automatically sorts long vegetables such as carrots into paper cans by weight sorting. This sorting device includes a hopper (1) that stores a large number of objects (a), and carries out the objects (a) to be sorted diagonally upward one by one at a predetermined pitch from the bottom of the hopper (1). an unloading section (2), a measuring section (3) connected to the conveying end portion of the unloading section (2) and serving as a measuring means for automatically measuring the weight while transversely conveying each object to be sorted (a); Part (3
) is comprised of a sorting section (5) as a sorting means that automatically sorts and collects into a plurality of collecting tools (4) as collecting sections based on the measurement results.

As shown in FIG. 1, the hopper (1) has a lower part shaped like a tapered funnel, and a material drop supply port (6) at the center of the lower end.
) is formed. In addition, a pair of rotating rollers (7a) and (7b) are arranged horizontally in parallel at a predetermined interval in this falling supply port (6), and the material to be sorted (a) is transferred to each roller (7a) and (7b). (7b) so as to be rotated in the direction of dropping downward through the gap. Due to the action of the rotating rollers (7a) and (7b), the conveyed object is placed in a position where its longitudinal direction is along the roller axis direction.
), (7b) falls from between.

A conveyance device (9) with a locking protrusion (8) is disposed below the rotating rollers (7a) and (7b) with its conveyance start end facing. This conveyance device (9)
The conveyor belt (10) is wound around a pair of upper and lower rollers (9a) and (9b), and this belt (10) is
Locking protrusions (8) are attached at predetermined pitches on the outer circumference of the conveyor belt 1-(1,0), and as the conveyor belt 1-(1,0) rotates, one locking protrusion (8) is attached to each locking protrusion (8). It is configured so that the object to be sorted (a) is placed thereon and conveyed diagonally upward.

As shown in FIG.
At the bottom of the conveyor belt (12) on which the material to be sorted (a) is placed and transported, there is a weighing platform (13) that is displaced downward by the weight of the material to be sorted (a).
The balance spring (14) and the damper mechanism (15) are used to bias the weighing platform (13) back to a predetermined position, and the differential transformer (1
6), so that the weight of the object to be sorted (a) can be automatically measured without stopping it.

The sorting section (5) is configured to separate
The paper is divided into stages and automatically collected into five collection tools (4). In other words, the sorting section (5)
A conveyor (18) is provided at the end of the conveyance of the measuring section (3) for continuous conveyance, and five conveyor belts are provided on the lateral side of the conveyor (18) for pushing out the objects (a) to be sorted laterally. Push-out tools (19) are arranged in parallel, and guide chutes (2
0) and each collection tool (4) are provided. Based on the measurement result of the measurement unit (3), the pushing tool (19) corresponding to equal paper separation is configured to automatically fall and collect the object to be sorted (a) into the corresponding collection tool (4). It is.

[Another example]

As described above, the configuration is such that the posture of the objects to be sorted (a) is consistently maintained from the unloading section (2) to the sorting section (5) with the longitudinal direction perpendicular to the conveying direction. As shown in FIG.
9) in the cross-feed conveying section (21) between the terminal end and the measuring section (3), as a posture changing means for changing the posture of the conveyed object in a direction in which the longitudinal direction of the conveyed object is along the conveying direction. A modification member (22) may also be provided.

With this configuration, the collection tool (
4) When it is pushed out and falls, it is guided while rolling, so there is less risk of damage.

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
